The United States Assay Commission was an agency of the United States government from 1792 to 1980. Its function was to annually supervise the testing of the gold, silver, and (in its final years) base metal coins produced by the United States Mint to ensure that they met specifications. The Mint Act of 1792 authorized the Assay Commission. Beginning in 1797, it met in most years at the Philadelphia Mint. Each year, the President of the United States appointed unpaid members, who would gather in Philadelphia to ensure the weight and fineness of silver and gold coins issued the previous year were to specifications. Although some members were designated by statute, for the most part the commission, which was freshly appointed each year, consisted of prominent Americans, including numismatists. Appointment to the Assay Commission was eagerly sought after—for one thing, commissioners received a commemorative medal, different each year, and, with the exception of the 1977 issue which was sold to the general public, extremely rare. In 1971, the commission met, but for the first time had no gold or silver to test, with the end of silver coinage for circulation. Beginning in 1977, President Jimmy Carter appointed no members of the public to the commission, and in 1980, he signed legislation abolishing it.
